SEWING-MACHINE ATTACHMENT FOR EMBROIDERING.

SPECIFICATION forming part of Letters Patent No. 360,896, dated April 12, 1887.

Application filed January .27, 1886. Serial No. 189,994. (No model.)

To all whom it may concern:

Be it known that I, EDWARD ALMERON MOON, a citizen of the United States, residing at Chicago, Illinois, have invented certain new 5 and useful Improvements in Sewing-Machine Attachments for Embroidering, of which the following is a specification.

. My invention relates to attachments for embroidering and to improvements in needleguards,whereby the needle may be more easily and safely used for'such work, and whereby the needle may be easily threaded when the guard is attached.

The objects of my invention are to accom- I plish the results above referred to by means of bobbins rotating about orconcentric with the needle-bar by a vertically reciprocating or vibrating spring needle-guard an'd presser-foot attached to the needle-bar, and by a needlethreading device which slides on the guard. I attain these objects by the means of the mechanism illustrated in the accompanying drawings, wherein--- Figurel is a side and part perspective view of a sewing-machine head with my improvements attached. Fig. 2 is a detail of the needle-guard and presserfoot with threading at- 'tachment. Fig. 3 is a detail of the embroidering device. Fig. 4 is a cross-sectionol' the same.

Like parts are indicated by the same letters in all the figures.

Ais the fly-wheel. B is a flexible shaft; 0,

.the arm of the machine; D, the table; E, a friction-wheel on the end of'the flexible shaft; F, a stationary ring secured to the resser-bar G, from which the presser-foot has been removed. Y

H is a ring which rotates on the stationary ring, carries the bobbins I I on arms, and is driven by the friction-pulley E.

J is a friction-wheel driven by the rotating wheel, and carrying the flexible shaft J.

J is a bobbin concentric with the needlebar, and rigidly supported in position, as shown.

Kis an arm extending downwardly from the part N and supporting the ring L, on which rotates the ring L, which is driven by the 50 friction-wheel J and carries the thread-congroove T, and has a hooked point to pass through the eye of the needle and engage the thread.

Vis a spring attached at one end to the sliding part N and at the other to the stationary part N The use and operation of my invention are as follows: The machine is set up without a presser-foot, as usually found in sewing-machines, and my devices, as shown, are attaehed. The power of the machine is then 4 applied through the flexible shafts to move the two rotating rings in opposite directions. The tension devices on the bobbin-carrying ring and the hooks on the lowerring serve to carry the threads across the track of the needle, where they are formed into a kind of cord and securely stitched to the fabric. The needle-guard and presser-foot operate to protect the hand of'the operator while working, to protect the point of the needle while the fab ric is moved about under it, and as a presserfoot. It flexibly bears on the fabric as the needle descends, and clears the needle as it8o rises from the fabric. The inner bobbin can easily be thrown out of gear and use. Either the bobbin-carrying ring or the concentric bobbin could be used independently. The needle-threader can be pushed down in its groove until the point projects through the eye of the needle. If, new, the thread be caught on the hook and the threader be withdrawn, the needle will be threaded. The motion of the reciprocating needle-bar could be used to drive the bobbins. The bobbins or their cords being carried in the manner shown across the track of the needle gives the work a plaid appearance.

' I claiml. A sewingmachine attachment consisting of a combined needle-protector and presserfoot having a centrally-perforated point-protector, through which the needle passes, and

an arm which is flexibly secured to and re- :00

ciprocates with the needle-bar, in combination with a needle adapted to reciprocate through such protector.

2. Asewing-maehine attachment consisting of a needle-guard and presser-foot, the supporting-arm having a curved groove, in combination with a hooked needle-threader, which reciprocates in the groove, in combination with a needle adapted to reciprocate through such protector.

3. A sewing-machine attachment consisting ofa bobbin concentric with the 1ieedle-bar,and a rotating thread-controlling ring having the exterior bobbins, I I, which has an arm and hooks adapted to carry the thread from the bobbin across the track of the needle, in combination with the thread controllers M M,

' eye-pointed needle, and reciprocating needlebar. v e 4. In asewing-maehine attachment, the combination of a rotating bobbin-carrying ring, a bobbin concentric with the needle-bar, threadcontrollers on the bobbin-carrying ring, and a rotating thread controlling ring below the bobbin,the thread-controllers adapted to carry the thread from all the bobbins across the track of the needle.

5. In a sewing-machine attach ment, the combination of a rotating bobbincarrying ring, a bobbin concentric with the needlebar, a flexible shaft which is rotated by the driving mechanism of the machine, and carries a friction-wheel which rotates the bobbin-carrying ring, an inner thread-controlling ring, and a friction wheel which communicates motion from the bobbin-carrying ring to the threadcontrolling ring, so that they rotate in opposite directions, and thus carry the thread across the track of the needle.
